RHSA-2014:0372: Important: Red Hat JBoss BRMS 6.0.1 update

Red Hat JBoss BRMS is a business rules management system for themanagement, storage, creation, modification, and deployment of JBoss Rules.This release of Red Hat JBoss BRMS 6.0.1 serves as a replacement for RedHat JBoss BRMS 6.0.0, and includes bug fixes and enhancements. Refer to theRed Hat JBoss BRMS 6.0.1 Release Notes for information on the mostsignificant of these changes. The Release Notes will be available shortlyat https://access.redhat.com/site/documentation/en-US/RedHatJBossBRMS/ The following security issues are fixed with this release:It was discovered that JBoss BRMS allowed remote authenticated users tosubmit arbitrary Java code in MVFLEX Expression Language (MVEL) or JBossRules expressions, resulting in arbitrary code execution within thesecurity context of the application server. Refer to the Solution sectionfor details on the fix for this issue. (CVE-2013-6468)It was found that XStream could deserialize arbitrary user-supplied XMLcontent, representing objects of any type. A remote attacker able to passXML to XStream could use this flaw to perform a variety of attacks,including remote code execution in the context of the server running theXStream application. (CVE-2013-7285)It was found that the Apache Camel XSLT component allowed XSL stylesheetsto call external Java methods. A remote attacker able to submit messages toa Camel route could use this flaw to perform arbitrary remote codeexecution in the context of the Camel server process. (CVE-2014-0003)It was found that RESTEasy was vulnerable to XML External Entity (XXE)attacks. If a remote attacker submitted a request containing an externalXML entity to a RESTEasy endpoint, the entity would be resolved, allowingthe attacker to read files accessible to the user running the applicationserver. This flaw affected DOM (Document Object Model) Document and JAXB(Java Architecture for XML Binding) input. (CVE-2011-5245, CVE-2012-0818)It was discovered that bouncycastle leaked timing information whendecrypting TLS/SSL protocol encrypted records when CBC-mode cipher suiteswere used. A remote attacker could possibly use this flaw to retrieve plaintext from the encrypted packets by using a TLS/SSL server as a paddingoracle. (CVE-2013-1624)It was found that the Apache Camel XSLT component would resolve entities inXML messages when transforming them using an XSLT route. A remote attackerable to submit messages to an XSLT Camel route could use this flaw to readfiles accessible to the user running the application server and,potentially, perform other more advanced XML External Entity (XXE) attacks.(CVE-2014-0002)The CVE-2014-0002 and CVE-2014-0003 issues were discovered by David Jorm ofthe Red Hat Security Response Team, and the CVE-2013-6468 issue wasdiscovered by Marc Schoenefeld of the Red Hat Security Response Team.Red Hat would like to thank Grégory Draperi for independently reportingCVE-2013-6468.All users of Red Hat JBoss BRMS 6.0.0 as provided from the Red Hat CustomerPortal are advised to upgrade to Red Hat JBoss BRMS 6.0.1.
